THE HEAD, ANTERIOR. 65 



anguli oris to the lower lip, and runs inward between the 

 mucous membrane and the orbicularis oris. It anasto- 

 moses with the opposite coronary artery and the arteries 

 below. (4) The superior coronary. Takes a similar course 

 along the upper lip. It supplies the upper lip and gives off 

 the artery of the septum of the nose. (5) The lateral nasal 

 artery. This is a small (sometimes a large) branch to the 

 side of the nose. It anastomoses with the nasal from the 

 ophthalmic, and with the facial branches adjacent. (6) The 

 angular artery. The last portion of the facial along the 

 side of the nose. It terminates at the inner angle of the 

 eye by anastomosing with the nasal branch of the ophthal- 

 mic. 



The facial anastomoses on the face. 



As already stated, the facial branches toward the middle 

 line freely communicate with each other. They also anas- 

 tomose with the artery next above and below (excepting 

 the coronary arteries do not anastomose with each other). 

 The other connections are, with the temporal, by the mas- 

 seteric and buccal branches uniting with the transverse 

 facial ; with the internal maxillary, through the inferior 

 labial and coronary joining with the mental (of the inferior 

 dental), by the muscular branches to the masseter and buc- 

 cinator from both arteries, and through the infra-orbital ; 

 and with the ophthalmic by its nasal branch anastomosing 

 with the artery of the septum, the lateral nasal, and angular 

 branches of the facial. 



DISSECTION. 



Cut the parotid gland away piecemeal, finish the facial nerve ; the upper 

 portion of the external carotid artery and its terminal branches, the temporal 

 and internal maxillary arteries ; the transverse facial artery and posterior auri- 

 cular arteries ; and the temporomaxillary vein or sinus.
